To'all whom it may concern:

Be it knownthat I, LEs E.'WILSON, a citizen of the United States, residing at Ferris, in the county of Fayette and State of 5 ,West Virginia, have invented a new and useful Improvement in Electrode-Holders for Electric Smelt' -Furnaces, of which the following is a spec' cation. o

My object is more especially to provide an electrode holder for use in electric furnaces,

where large units of electric power are re. quired, and of an improved constructionadapting it for holding a plurality of carbon ncils and for distributing the current uniormly thereto.

It 1s also my object to provide a holder which will ermit a pencil, or ncil'section, to be placed in position and ad usted without the necessity of removing'the holder or of cutting off the current to the pencils in the hoiderl.l dr

n-t e awing Fig'u're 1 is a broken top plan view of mydmproved holder, adapted or sustaining and distributing current to six carbon penc1ls;'Fig. 2, a reduced section taken on line 2 in Fig. 1 and showing the holder with pencils fastened therein, in com bination with an electric-furnace crucible; Fig. 3, an enlarged plan-section of one-half the holder, the section being taken-on line 3, in Fig. 2 and Fig. '4, a broken section taken on line 4, in-Fi 1.

The holder Shown is formed of six similarly constructed segments, 5,. formed with smooth meeting faces and which when placed together constituted a complete circular head.

' Extending through each segmentis anopenister when the sections are Bolts, 13, are passed'throug the sai ing the-wall of each openi lies at opposite meeting edges, upwardl pro.-

ing, 6, presenti the semi-circular surface,7, and space/8. ntering through the sideof the head to the space, 8, is a threaded ,open-' ing, 9, fitted with a set-screw, 10. Surround 6, is a chamber,

1 1, cored in the segment. ach segment caroca ted as s own,

aving bolt receiving perforations which regp'l'aced together.

ecting' attaching lugs, 12,

tenng o enings, and-nuts, 14, upon the b ts,

serve wIth-"thebolts to clamp thesections se-.'

curelytogether. "In the top of'each section;

close to-opposite sides of its chamber, 11, are. pipe rece ving openings, Extending to two vof said opemn(gs,; m adjacent sections, are

water inlet an utlet pi 15, while connecting'the adjacent opemngs of the sections,

are short water-conducting pipes, 16. The water entering at one pipe, 15, will pass through all the chambers, 11, in series and escape at the other pipe; 15. In each space, 8, is a hollow segmental follower or pencilclamping block, 17 engaged by the set-screw,

10. Water inlet and outlet pi es, 18, communicate with two adjacent ollowers, 17,"

and all the chambers of the.followers are connected in series by pipes, 19, whereby water entering through one pipe, 18, will pass through all the followers and escape at the other pipe, 18. Thehead is suspended from a cable, 20, which is secured at its lower end to apreferably triangular, and preferably copper, block, 21, provided along each edge with attaching plates, -22, for conducting wires, 23, ,leadin from the source of electricwcur- Securedto and extending suspendingHconductor-bars, tened to t cc of the segments, 5, at polnts equidistant apart. I v To fasten a carbon pencil, 25, in place, it'is passed down'ward'through an opemng, 6, between the surface, 7, and follower, 17, and clamped by tightenin the set-screw, 10, against the follower. his ivesa lar e surface contact between the ho der and t e op.-

rent sup I downward fi om the sides of the blockfll, are 24, securely .fas-

posite sides-of each. pencil. The ,pencils I p employ are of the sectional type and each section may be formed, as indlcated, with a threaded projection, or joint-member, 26,.at

one end and a threaded socket or j oint-merm ber, 27 in the other end.

In Fig. 2'I show a crucible, 28, havmg a carbon electrode, 29, in its base resting upon a current-conducting base-plate, 30. On the base-plate is connecting means,31, for the electric circuit wires, 32. Fitting over the crucible is a water-jacketedcover, 33, hav-- 0 e s through it for the assage of the mods and 7 for feeding materia to the crucie.

. In ractice as the pencils wear away at My improved head makes it possible to electric current conducting means connected f .a single controlling means. tions may be-inserted as desired, without in;

mount avlarge number of pencil electrodes in a compact cluster, and to distribute large unitsof electric energy through the encils, thus, in the present construction, if t e carbon pencils are .capable of conductin 2,000 electric H. P. each, 12000 electric H. may be supplied from a single head, governed by New pencil secany way disturbing the operation of the furnace and without danger to the attendant. If it is desired to operate the furnace continuously in the smelting of ores, tap-holes may be provided in the sides of the crucible for drawing ofi the metal and slag as they accu-, mulate. By constructing the pencils in sec tions and feeding them as desired, there is practicall no unnecessar Waste of the pencilsdand ah the material tliereof may be util- 1ze What I claim as new and desire to secure by Letters Patent is 1. In an electric-furnace encil-electrode holder, the combination of c am ing means for releasably engaging a cue and provided with an opening there or, and a pencil formed of longltudinal sections joined together with the upper section provided with ajoint-member and releasably held by said clamping means in said opening .to adapt it for coupling to said joint-member another section equippled with a joint-member to engage therewlt for the purpose set forth.

2. An electric furnace current distrib-' uting holder for apluralit of pencil electrodes, comprising, in com inat1on, a head having pencil receiving openings through it,

with the head, anda pencil-suplport, comprisin current-conducting penc' engaging and re easing clamping means on the head at each of said openings.

' 3. An electricfurnace current distrib-" uting holder .for'a plurality of pencil electrodes, comprising, lil combination, a water jacketed head having pencil receiving openings through it, electric current conducting means connected with the head, and a pencilsupport, comprising water-jacketed pencil engaging "and releasing clamping means on the head ateach of said-openings.

4. In an electric furnace, the combination of.a current distributing holder for a plurality of pencil electrodes, comprising, a head having pencil receiving openings through it, electric-current conductin means connected with the head, and penci engaging and re leasing clamping means on the head at said openings, and pencils formed of longitudinal sections fastened together at their ends passing throu h said openin s and adjustably fastened t erein by said c amping means.

5. An electric, furnace current-distributingholderforapluralityofpencilelectrodes,

com rising, in combination, apencil-supporting ead connected with the electric-current supply and having an opening through it for eac pencil, each opening being formed with V a segmental wall against which the pencil fits at one side, an adjustable clamping block in each opening against which the pencil fits at its opposite side, and setscrews in the sides of the head engaging said blocks, whereb each pencil may be positioned indepen ently of the others.

uting holder for a plurality of pencil electrodes, com risin 1n combmation, a pencil sup orting ead ormed of a plurality of inte tting segments secured together, electriccurrent conducting means connected with the head, the segments having openinflgs I through them for the passage of the penc and pencil engagingand re easing clamping meanson the sections at each of said open- 6.
